Carbon and Helium
Oxygen and Hydrogen
Carbon and Hydrogen
Lead and Hydrogen
Which of the following is true about plastic?
It's cheap
It's versatile (many uses)
It's disposable
All of the above
True or False: Large pieces of plastic break down into smaller pieces in the ocean
True
False
The hydrocarbons that leave the top of the fractioning column are
solids
liquids
gases
What is the first state change that happens in the fractioning column?
evaporation
condensation
melting
What process happens at each level in the fractionating column?
Evaporation
Condensation
Combustion
What process is used to separate crude oil in hydrocarbons with different chain lengths?
distillation
fractional distillation
cracking
polymerisation
What do scientists call plastics when they break down into tiny pieces?
Microtrash
Microplastics
Microparticles
Macroplastics
How does plastic trash cause marine life and sea birds to starve?
They mistake plastic for food, which clogs their stomachs and doesn't leave any room for real food.
Plastic takes up space in the water so marine animals have no place to live.
The plastic in the ocean is so dense that the marine life cannot find food easily.
Plastic doesn't cause marine life or sea bird to starve: they're smart enough to know the difference between plastic and food.
